29 Claims. (01. 101-58) This invention relates to selectors of the kind controlling the operation of printing machines and the like through which devices, having identifying means thereon in the nature of tabs, 1a-

cuna, or the like, are sequentially passed. The selector cooperates with the identifying means to separate or otherwise control the devices or to control the operation of the machine. For xample, in a printing machine, all of the printing devices passed therethrough are not always used in a printing operation and this is accomplished by selecting which of the printing devices are to be used in a printing operation and which are not to be used or, as it is termed, skipped. Further examples of selection in a printing machine are: The separation or other segregation or identiflcation of the sheets being printed; stopping the operation of the machine under predetermined conditions; controlling the operation of a numbering or dating device; controlling the operation of a signal; controlling the operation of a multiplicating arrangement whereby a number of impressions may be made from the same printing device; controlling the operation of mechanisms operating on the sheets such as, means for orienting the sheets in printing position,

means for severing sheets from a web, means for moving the sheets to distribute the impressions,

a printing couple acting on the sheets, and other similar mechanisms; controlling the number of sheets to be printed from a selected printing device; controlling an auxiliary printing mechanism; and determining the operating characteristics of the platen or other printing member.

The period in the cycle of operation of the machine which may be devoted to the performance of the selection is relatively short and consequently it is of importance that the selection be performed in a rapid manner. Moreover, the detector of the selector must be sensitive to insure accuracy of operation and this is somewhat difiicult to attain by reason of the wear to which the detector is subjected and also by reason of the inertia of the detector in the operative move- 45 ment thereof. One of the salient objects of my invention is to provide a selector embodying a sensitive detector capable of rapid operation.

A variation from the proper position of the identifying means may interfere with the selection, especially where the sensing operation of the detecting means requires that the detecting means contact the identifying means. Hence, another object is to provide a selector which will operate in a positive manner irrespective of slight displacement of the identfiying means.

"A further object is to use light to control the operation of the selector to thereby increase the speed of operation and to permit detection either during movement of the members carrying the identifying means or while this movement is momentarily arrested.

A still further object is to provide a selector embodying a removable part for determining which of the identifying means are to control the selection.

Still further objects are to provide a selector embodying a minimum'number of moving parts so that error by reason of inertia or momentum of moving parts may be eliminated; and which selector will be simple and-economical in construction and eflicient and positive in operation.

A frequent use of a selector is in a printing machine wherein the selector functions to control the printing operations of the machine.

2 aoaaass The printing devices are sequentially passed through the machine and have identifying means thereon and the selector cooperates with the identifying means to determine whether a print- 5 ing device is to be printed or skipped upon movement thereof into printing position.

In Figs. 1 to 7 of the accompanying drawings I have shown my invention in association with a printing machine embodying a main frame 3 hav- 10 ing at the upper end thereof a bed 3 on which the printing operations are performed. A bracket on the main frame provides a bearing in which a shaft I3 is Journaled and rotatably mounted on this shaft is a flywheel (not shown). Power is 1 transmitted to the flywheel from a suitable source and a clutch structure (not shown) interconnects the flywheel and the shaft. Another clutch structure ll serves to connect the spur gear l2 to the shaft l3. The spur gear I2 meshes with a spur gear I! fast on the shaft I4. Also fast on the shaft i4. is a miter gear l6 meshing with a miter gear l6 fixed on the cam shaft I'l journaled in suitable bearings in the frame 3. Fast on the shaft I3 is a miter gear i3 meshing with a miter gear i6 fast on the platen shaft 23, journaled in suitable bearings in the frame 3.

Fast on the shaft 23 is an eccentric 2| (Fig. 3) surrounded by an eccentric strap 22 carrying a connecting rod 23 to which one arm 24 of the plate drive rocker 26 is pivotally connected. At the free end of the rocker 26 is a pawl 26 including a recessed nose 21 adapted to successively engage pins 23 on the sprocket 26 mounted on the shaft 33. Also fast on the shaft 30 is another sprocket (not shown) and the printing device feed chains 3| are directed around these sprockets. As the shaft 20 rotates, a recipro-' catory movement is imparted by the eccentric 2| to the connecting rod to so operate the rocker 25 that the recessed nose 21 of the pawl 26 successively engages the pins 28 to impart a step-by-step movement to the sprocket 29. This step-by-step movement imparted to the sprocket is transmitted to the printing device feed chains 3| extending along the printing device guideway. The chains withdraw the printing devices from the magazine M, arranged at one end of the printing device guideways, and move the printing devices, indicated by D, through the guideways into printing position over an anvil such as that indicated by A in Fig. 8.

Impressions are made from the printing device disposed over the anvil by the platen P. After the impression has been made from the printing device positioned on the anvil, the printing device feed chains operate to discharge this printing device into the usual printing device 00 collecting galley.

The platen P is carried by the arm 32 of the rocker 33 pivotally mounted at 34 on the frame 6. The rocker 33 includes two arms 36 and 36 carrying rollers 31 and 38 respectively engaged 5 with the peripheries of conjugated cams 39 and 43 fast on a sleeve 4|, surrounding the shaft 26. and adapted to be connected to said shaft, as will be described. When the sleeve is con nected to the shaft to rotate therewith the cams 70 act on the rollers to motivate the rocker 33 and thereby move the platen P into and from printing position to make an impression, through the usual ink ribbon, from the printing device on the anvil. 7 Connection between the sleeve 4| and the shaft 23 is contr gled through a clutch including the disc 42 fast on the shaft 23 and having a pawl 43 pivotally mounted thereon. A spring 44 acts on the pawl and urges the nose 43 thereof into engagement with the lug 46 fast on the sleeve 4|. In this manner the sleeve 4| is driven with the shaft 23 for power will be transmitted from the shaft to the disc 42 through the pawl 43 to the lug 46.

To disconnect the sleeve from the shaft a throwout arm 41 is provided which engages the tail of the pawl 43 to disconnect the nose 46 from the lug 46. The throwout arm 41 is carried by the rocker 43 pivotally mounted on the shaft 43 carried by the frame 6. The rocker 43 also includes an arm 33 carrying a plate 3i having a notched nose 62. One end of a spring 64 is connected to an anchor 63 on the rocker 43 and the other end of this spring is connected to the spring anchor 66 on the frame 3. The spring 64 acts on the rocker 43 to turn the same in a counter-clockwise direction, as viewed in Fig. 3, about the shaft 43, this action being limited by the engagement of the nut 61 on the restoring rod with the stud 63 on the connecting rod 23 and through which stud the rod 36 is passed. The upper end of the rod 63 is pivotally connected to an arm 63 on the rocker 43. A

latch pawl 63 is pivotally mounted on the frame 3 at 6| and has a notch 62 therein into which the notched end 62 on the plate 6| may be extended. Secured to the underside of the latch pawl is a leaf spring 63 carrying a rider 64, engageable with the arcuate face of the index segment 65 pivotally mounted at 66. In the arcuate face of the index segment 66 is a notch 61 into which the rider 64 may move under certain conditions of operation as will be explained. Unitary with the index segment 66 is an arm 63 having a bearing at the free end thereof in which a shaft 10 is Journaled.

On this shaft 10 is a knob ll having indicating indicia thereon which in the present instance comprises the letters P and S. Eccentrically connected to the shaft 13 is the upper end of a link 12, the lower end of which is connected to the arm I3 of the bell crank 14 pivotally mounted at 15 on the frame 3 and including an arm 16 providing an armature for the electro-magnet 11.

When the knob II is disposed as illustrated in Figs. 2 and 3 the indicia S is in uppermost position and by reason of the eccentric connection between the shaft 13 and the link 12 the arm 63 will be so positioned that the index segment 66 will be so arranged that the nose of the rider 64 will normally be disposed in the notch 61. However, should the knob H be turned so that the indicia P is in uppermost position the Just described parts will be so positioned that the nose of the rider 64 will rest on the portion 13 of the index segment 66 at the left hand edge of the notch 61 as viewed in Fig. 3.

When the throwout arm 41 is positioned in the path of the tail of the pawl 43, the nose 43 of the pawl is disengaged from the lug 46 and this occurs when the notched nose 62 on the plate 5| is latched in the notch 62 in the latch pawl 63. When, however, this notched nose is not latched in this notch 62, the throwout arm 41 is held out of the path of the tail of the pawl 43 and consequently the nose 46 is not disengaged from the lug 46. Since the platen P is only operated when the sleeve 4i moves with the shaft 23 and as the sleeve turns with this shaft only when the nose 46 engages the lug.

46 it is apparent that the operation-of the platen may be controlled by the engagement of this nose with this lug.

The operation of the platen is so controlled in order that only determined oi the printing devices moving into printing position will be used in a printing operation. This control of the printing operation is determined from the printing devices which may have tabs T thereon or which may be provided with lacuna or other identifying means. In the illustrated embodiment of the invention the printing device D (Fig. has two tabs T thereon and only printthose disclosed will be selected, that is, used in a printing operation when the mechanism is arranged as will now be explained.

Selection has been brought about in the art heretofore by the use of sensing means which contact identifying means on the printing devices but I have supplanted such sensing means or detectors by an improved structure, one form of which is disclosed herein. The selection has usually been determined by the detector of the selector from the printing device immediately behind the one positioned on the anvil. Further. the selection has usually been performed during the time the platen P was making an impression from the printing device on the anvil, that is, the device in printing position, so that-in the next cycle of operation of the machine the selector would be set up and could therefore so effect operation that the printing device was printed or skipped, dependent upon its characteristics. For the purpose of describing this invention I show the detector of my selector positioned to similarly cooperate with the printing devices.

It is an object of my invention to provide a selector which may be very expeditiously set up. To attain this I provide cooperating guideways 19 in which a control device such as the matrix may be removably mounted. The

, guideways are so located in the machine that the matrix will be disposed above the tabs or other identifying means on the printing device immediately behind the printing device in printing position, .in other words, the printing device in selector position. In the present instance the matrix consists of a flat strip of opaque material in which openings are provided to afford unimpeded light passage at selected positions and the matrix may have as many openings as there are positions for identifying means on the printing devices. If, for example, provision is made on the printing device for twelve tabs, provision will be made in the matrix for twelve openings but it is to be understood that a greater or less number of openings may be provided as required without departing from the purview of my invention.

Light is supplied from a lamp L which has associated therewith, in the present instance, a suitable parabolic reflector 8|, this lamp and reflector being mounted at the upper end of a housing 82 and being spaced from the matrix a determined distance. Arranged intermediate the lamp and the matrix is a lens 83, the focal point of which is substantially in the plane of the matrix and this lens directs an elongated beam of light onto the portion of the matrix whereat the openings are to be provided. Below the printing device guideway, in vertical alignment with the matrix 80, I provide a photo-electric cell 84 or other light sensitive means and light passing through the openings in the matrix may pass to'this light sensitive means provided'it'ls not blocked oil, in the illustrated embodiment of the invention, by tabs T. Ii there is an opening in the matrix and there is no tab below.this opening, the light will pass to and activate the photoelectric cell which is connected in a suitable electric circuit controlling the operation of the electro-magnet 'II.

One such circuit is disclosed in Fig. 4 and therein line wires 85 and 86 are connected to the primary winding 81 of the transformer 88 which includes a secondary winding 89. The conductor 90 is connected to one end of the secondary winding 89 and to a terminal 5. A conductor 9i is connected to the terminal III and to a conductor 9I' which is connected to the cathode 92 of the grid-glow tube 93. A conductor 94 is connected to the grid 95 of the tube 93 and a conductor 96 interconnects the conductor 9i and the conductor 94. Connected in series in the conductor 96 is a condenser 91 and a resistance 91'. The conductor 94 is also connected to the cathode 98 of the photo-electric cell 84. A conductor 99 is connected to the anode of the photo-electric cell and a conductor I00 is connected to the anode of the grid-glow tube 93. A conductor MI is connected to the conductors 99 and I00 and to the terminal IIB. A conductor I02 is connected to the terminal H6 and to one end of the winding of the relay I03, a conductor I03 having a resistance I04 therein being connected to the other terminal of the winding of the relay I08 and to the other terminal of the secondary winding 89.

A characteristic of a grid-glow tube is that, when it is connected in a circuit and the grid thereof is not connected for discharge, the grid will assume a negative potential. To insure that the grid 95 of the tube 93 will have a negative potential, a by-pass is provided between the cathode 92 and the grid through the conductor 9I', conductor 96, resistance 91', condenser 9'I, and conductor 94. When the grid has a negative potential impressed thereon, current will not flow through the grid-glow tube 93 because the negative potential on the grid will oppose any discharge from the cathode. However, when light passes to the photo-electric cell, as when there are no tabs below the openings in the matrix, it will be activated and consequently the circuit will be closed therethrough. The closing of the circuit through the photo-electric cell affords a discharge for the grid 95, as current may flow therefrom through the conductor 94 to the cathode 98 and thence to the anode of the photo-electric cell and through the conductor 99. This discharge causes the grid-glow tube to break down since there will no longer be a negative potential on the grid 95 and consequently a circuit will be established therethrough which will energize the relay I03, the armature of which carries a bridge contact I04 that will close the circuit between the contacts I05 and I06.

The contacts I05 and I06 are arranged in a circuit including line wires I01 and I08. The line wire I01 is connected to one end of the winding of the electro-magnet I1 and the line wire I08 is connected to the terminal I05. A conductor I09 interconnects the other end of the winding of the magnet 11 with the contact I06.

Consequently, when circuit is closed between the contacts I05 and I06, the electro-magnet 11 is energized and it therefore attracts the arm 13, which is in the nature of an armature, and turns the bell crank I4 against the action of the spring IIII, which normally acts on the bell crank 14 to urge the arm I3 thereof into en-. gagement with the stop pin III (Fig. 3) carried bythe frame 3. Thus, when the'arm I3 is attracted by the electro-magnet 11, the bell crank I4 is turned to rotate the index segment 35 into the position illustrated in Fig. 3 and in so doing the rider 64 is moved out of the notch 31 and rests on the arcuate face of the index segment adjacent the edge of the notch. When the rider 34 is moved out of the notch in this manner, it acts through the leaf spring 33 to so turn the latch pawl 80 that the notch 82 is moved into a position whereat the notched nose 52 may seat and latch therein to thereby position the throwout arm 41 in the path of the tail of the pawl 43 which as previously described, disconnects the nose 45 from the lug 43 and therefore the sleeve 4| does not turn with the shaft 20 and as a result the platen P is not operated and consequently the printing device which has been in selector position will not be printed when it is moved into printing position.

During the cycle of the machine which would normally print from this printing device the connecting rod 23 moves upwardly and moves the restoring rod 56 upwardly, and this imparts movement to the rocker 48 whereby the notched nose 52 will be disengaged from the notch 62 if the parts are not to be latched on the next cycle of'operation. However, the selection operation for this cycle of operation will have been performed just prior to this time and if the parts are to remain latched on the next cycle of operation, as when the succeeding printing device is also to be skipped, this upward movement of the restoring rod 56 will not release the parts.

If the printing device in selector position is tabbed in accordance with the disclosure in Fig. 5 it is apparent that there will be tabs below the two openings in the matrix. Consequently, no light will pass to the photoelectric cell and as a result the grid 85 will not be discharged'and therefore the circuit to the relay I03 will remain open. Thus, the notched nose 52 will not be latched in the notch 62 and the throwout arm 41 will not engage the tail of the pawl 43 and consequently the sleeve 4| will rotate with the shaft 20 and the platen P will be operated.

It may be desirable to reverse the foregoing selection; that is, to skip printing devices having tabs thereon corresponding to the tabs on the printing device illustrated in Fig. 5, and this may be done by rotating the knob II to position the indicia P in upper position. The link I2 is eccentrically connected to the shaft III and the position of the bell crank 14 is determined. Consequently, when the knob II is turned, the relative position of the arm 68 and the index segment 65 is varied. When this is done the rider 64 is normally positioned on the portion 18, and the latch pawl 60 is normally held in an upper position whereat the notched nose 52 will latch in the notch 32 unless the rider 34 moves into the notch 61. When the parts are so arranged the platen P will not be operated unless the relay I1 is energized, for when this occurs, the parts will be moved so that the notch 61 will u be below the rider 64 and this will permit the latchpawlsltopivctdownwardiqastherider moves into the notch.

Itisapparentthatpassage'oflighttothe photo-electric cell controls the operation of the platen whether the printing devices are to be skipped or printed. The mechanical parts of the selector described herein can only be latched at a certain time in the cycle of operation of the machine but it is to be understood that the use of the described manner of detecting is not limited to a selector of this structure.

Moreover the .lamp may be rendered operative only at the time the detection is to be performed and, also the photo-electric cell and the grid glow tube need only be operative while the detection is being performed. Consequently, I provide a timing switch which will render the devices operative only at the time of detection.

One form of timing switch'is illustrated in Fig. 3 and includes the spaced contacts III and H3. The contacts are closed and opened by an adjusting screw III having an insulated end portion 6', this adjusting screw being carried bya lug II4 onthe rocker 2|. At the time the selection is to be performed, the rocker 23 is so positioned that the lug II4 will move the insulated end portion III into engag ment with the contact .I I3 and force the same into eng sement with the contact II2 to thereby close the circuit. In the present instance, I provide the contacts H2 and H3 in the line wire ll and the circuit including this wire is closed only while the detection is being performed.

I have described how the selector may be reversed mechanically but the reversing may also be brought about electrically and under certain conditions of operation it may be an advantage to do this, for it would only entail the operation of a switch. In Fig. 7 I have disclosed the electrical connections to be used when such a reverse is desired and in Fig. 6 I have shown one form of switchwhich may be used to bring about this reverse. In the electrical connections disclosed in Fig. 7, a circuit similar to that shown in Fig. 4 is included and when the various switches are arranged as shown in dotted lines in Fig. 7, the mechanism will function when the photo-electric cell is activated, for under this arrangement circuit through the grid-glow tube is normally open, but when the switches are arranged as shown in full lines in Fig. 'I circuit through the grid-glow tube is normally closed and is opened when light through to the photo-electric cell.

The electrical connections disclosed in Fig. 7 are to be used with the circuit disclosed in Fig. 4, wires III and HI of these electrical connections being respectively connected to the terminals I I I and HE. A conductor III is connected to the line wire III, the cathode II! of the grid-glow tube I20 and to a contact I2I. A conductor I22 extends between the conductor III and the contact I23. A conductor I2! is connected to the grid I24 of the tube I20 and also to a contact I28. A conductor I21 extends between the conductor I25 and the contact I23 and a resistance I29 and a fixed condenser I33 and connected in series in this conductor. The wire I3I extends to a terminal I35. A conductor I33 interconnects the terminal I35 and the anode I34 of the tube. -A conductor I33 interconnects the terminal I35 and the contact I31. A conductor I 38 interconnects the contacts I33 and I43 and is also connected to the anode I43 of the photoaoeaaas elecnic cell Ill. A conductor Ill interconnects the contact Ill and the contact I, and a conductor Il1 interconnects the conductor Ill and the cathode I of the cell Ill. Spaced from the contact I2I is a dead contact I68 and this contact is also spaced from the contact I31 (see P 8. 6). i

When the various switches are arranged as shown in full lines in Fig. 7, the circuit through the grid-glow tube I20 is normally closed, current flowing from the terminal II6 through conductors H1 and III to the cathode H9 and thence through the tube to the anode I3l and through conductors 133 and I3I to the terminal H6 and therefore circuit to the relay I03 is closed which closes the circuit to the electro-magnet 11 and therefore the arm 16 is normally attracted and the devices are operated as previously described.

When, however, light activates the photo-electric cell Ill, current flows from the anode through the conductor I38, contact 3, switch blade I50, contact I26, conductor I25, to the grid I2l to thereby impress a negative potential on the grid I2l which opposes discharge from the cathode I I9 and consequently the circuit through the grid-glow tube is opened. Connection between the anode H0 and the conductor I3I is broken by reason of the fact that the switch blade I53 is disposed on the dead contact H9. The cathode H9 is connected to the cathode 8 through conductor Ill, contact I2I, switch blade I52, contact 6, and conductor 1. A by-pass is provided between the grid I2l and the conductor I3I so that the current value of the impressed negative potential may be kept at a minimum, this by-pass being afforded by the'conductor I25, condenser I30, resistance I29, conductor I21, contact I28, switch blade II, contact I85 to conductor I3l.

However, when the switches are arranged in the dotted-line position, the mechanism is arranged as shown in Fig. 4 and it functions in the manner described, the electrical connections being as follows: the grid I2l is connected to i the cathode Ill through the conductor I25, contact I26, switch blade I50, contact 5, conductor Ill, and conductor 1. A by-pass between the grid I26 and the cathode H8 is provided by conductor I25, condenser I30, resistance I29, conductor I21, contact I26, switch blade I5I, contact I23, conductor I22, and conductor II8. In order that the cathode II9 will not be connected to the cathode N8 the switch blade I52 is moved into the dotted-line position and engages the dead contact 9. The anode M0 is connected to the conductor I3I through conductor I38, switch blade I53, and conductor I36, and it is therefore apparent that the electrical connections in this instance are like those disclosed in Fig. 4 and consequently the device will function in a like manner.

'In the foregoing description I have described a selector controlling the printing operation in a printing machine. I have previously stated, however, that the invention is not necessarily limited to this control of they printing operation and also that the invention is not limited to use with a printing machine. It is often desirable, in machines of the kind through which devices having identifying means thereon are passed, to separate the devices. For example, in the patent to Joseph S. Duncan, No. 1,299,437, patented April 8, 1919, there is shown a printing machine wherein the printing devices are passed into selected galleys after they have passed through printing position in the machine and this separation of the printing devices is controlled by a mechanical detector acting "onidentifying means on the printing devices. It is within the ambit of my invention to substitute a detecting arrangement, similar to that which I have described herein, for the mechanical detector shown in that patent. Furthermore, this separating of the devices having identifying means thereon may be done prior to passage of the devices into operative position in the machine.

An arrangement such as that disclosed in the aforesaid Duncan Patent 1,299,437 is fragmentally illustrated in Figs. 8 and 9 wherein a chute I60 is shown immediately forward of the anvil A. The printing devices D pass into the chute from the anvil, on which the printing devices are positioned when impressions are made therefrom by the platen P in the manner previously explained.

A gate IN is provided in the chute I60 and y of these trays is filled with printing devices it may be removed and another tray is then substituted therefor.

A packer frame I65 of the kind well understood in the art is provided which includes, depending fingers as I66. As each printing device is delivered into the tray IN the packer frame is operated to force the printing device rearwardly in the tray; The packer frame is pivotally mounted at I61 and is also provided with depending fingers I68 which force the printing devices delivered into the tray I63 rearwardly in this tray. The packer frame I65 as is well understood in the art operates in timed relation with the delivery of the printing devices into the trays.

The rod I69, on which the gate I6I is mounted, is provided at one end with a yoke I10 (Fig. 9). An arm l1-I is loosely mounted on the rod I69 between the arms of the yoke. An adjustable screw I12 in one arm of the yoke engages the arm I" and a spring I13 is disposed between the arm "I and the other arm of the yoke. A spring I" is connected to the arm "I and to the frame of the machine and normally holds the rod I1] and consequently the gate I6I in the position indicated in Fig. 8.

In the illustrated form of the invention it is desired to pass all printing devices that are to be usedagain through the chute I62 into the tray I63 and to deflect those printing devices that are not to be used again into the portion I60 of the chute I60 and thence into the tray I6l. Obviously this plan may be reversed if desired. In the machine as shown, however, it is necessary to shift the gate I6I after every impression taken from a printing device which is to be deposited in the tray I. The gate is left in its normal position shown in Fig. 8 after each impression from the printing device which is to be deposited in the tray I63. This is under control of the selector mechanism of this invention and in the manner previously described the electro-magnet 11 is energized when the selector cooperates with printing devices D having tabs T in a predetermined position. All printing devices having tabs Tin a predetermined position so as to effect energization of the electro-magnet 11 aredelivered into the tray I64. All other printing devices are is delivered intothe tray I83. This operation may,

of course, be reversed if desired. Hence whenever the selector mechanism, which may be located for the purpose of controlling the gate III at printing position, cooperates with a printing device having a tab Tin a predetermined position the gate IN is shifted.

To this end a shaft I1! is mounted in the frame of the machine and is driven from the drive shaft 28 in synchronism therewith by a chain I 18 di- 15 rected about sprockets (not shown) on the shafts 28 and I15. A collar I11 is fast on the shaft I18 and a cam I18 is rotatably mounted on the shaft adjacent said collar. Normally a dog I19 pivotally mounted on the cam I18 is seated in the go-notch- I88 in the collar I11 under the action of the spring I8I. Thedog is unseated from-the notch I88 by engagement thereof with the throwout arm I86. Upon each revolution of the shaft 28 the shaft I15 makes a revolution as does the cam I18 when the dog is seated in the notch. The cam I18 engages a roller I82 on the arm "I and is provided with a high portion followed by a slight depression. As this high portion passes the roller I82 the arm I1I causes the yoke I18 30 to swing, thus moving the gate I8I to the right as viewed in Fig. 8. The cam is timed, however, so that normally the roller I82 rests on a low portion thereof when a printing device reaches the delivery end of the printing device guideway and therefore the printing device will normally pass through the chutes I68 and I82 into the tray- I63.

A rocker I83 pivoted at I84 on the frame of the machine has a roller I85 thereon that is normally held in engagement with the throwout arm I 88 by the spring I81. A link I88 is connected to the rocker I83 and to the free end of the arm 12 of the bell crank 14, the arm 18 of which bell crank is the armature of the electro-magnet 11. Thus whenever the electro-magnet 11 is energlzed the armature 16 thereof is attracted whereupon the bell crank 14 pivots, and this movement is transmitted from arm 12 thereof through link I88 to rocker I83 which thereupon so pivots that the roller I85 acts on the throwout arm I 88 to so position this throwout arm that it engages the tail of the dog I19 which is thereupon unseated from the notch H8. This uncoupling occurs just as the roller I82 drops into the depression following the high point of the cam I18 and the gate I6I is thereupon moved to the right, as viewed in Fig. 8, and held there during the following revolution of the shaft 28, that is to say, while a printing device is discharged into the chute I 68. The printing device in this instance therefore passes through the portion I68 of the chute into the tray I84.

If in the next cycle of operation the electromagnet 11 is not energized the throwout arm I86 will not engage the tail of the dog I19 and the pawl will therefore reseat in the notch I88 and again start rotation of the cam I18 which will again cause the gate I 6I to be seated in its normalposition shown in Fig. 8. If, however, the

effects energization of the electro-magnet 11, the throwout arm again engages the tail of the dog I 19 and it is prevented from seating in the notch 7 I88 wherefore the gate I6I remains positioned to succeeding printing device is so tabbed that it direct the succeeding printing device into the tray I84. I

Thus the mechanism disclosed in the Duncan Patent 1,299,437 can be readily controlled by the selector disclosed herein, it only being necessary to supplant the mechanically operating devices of the Duncan-patent by devices controlling the electro-magnet 11.

In the application of Emmett C. Hartley, Serial No. 535,818, filed May 8, 1931, now Patent 2,002,737, patented May 28, 1935, there is shown the control of a number of mechanisms in a printing machine by a detector cooperatingv with identifying means on the printing devices. In this application "a selector having features in common with the selector disclosed in the present application is described and it is therefore readily apparent that the detector of the selector of that application may easily be supplanted by the detector shown herein,including the light sensitive means.-

The machine shown in the aforesaid Hartley application is of the kind wherein bill sections .such as utility bills, insurance notices and the like are printed. In machines of the kind therein illustrated the bill sections are severed from a web and impressions are usually made on both faces thereof from permanent printing forms in the machine. Impressions are also made on the bill sections from printing devices sequentially passed through printing position in the machine. The printing devices, as in previously described forms of the invention, are withdrawn from a magazine in the machine and passed into printing position. These printing devices like those previously described bear identifying means such as tabs and the machine is under control of a selector responsive to such identifying means on the printing devices.

In the normal operation of the machine the successive passage of the bill sections and the sequential passage 'of the printing devices are in timed relation which must be maintained to insure proper operation of the machine. Thus if a printing device is not to be used in a printing operation upon movement thereof into printing position, the printing device feeding mechanism must be operated in a normal manner while operation of the other mechanisms is interrupted.

The machine illustrated in the aforesaid Hartley application is of the kind disclosed in another co-pending Hartley application, 459,599, filed June 6, 1930, now Patent 2,041,183, patented May 19, 1936, to which reference may be made for the details of construction of the machine.

The machine, however, as illustrated in Figs. 10, 11, 12 and 13 hereof includes a printing couple embodying a printing cylinder I98 which, in the present instance, has a platen cylinder (not shown) in vertical alignment therewith. A web is withdrawn from a suitably supported roll and passed through this printing couple and thence to a pair of vertically aligned feeding rollers, the roller I9I of which is illustrated in Fig. 10. The web passes from the feeding rollers as I9I through a severing device comprising a stationary knife I92 and a movable knife I93.

Power is supplied to the machine from an electric motor or other source of power through a belt I94 directed about a flywheel I95 that is freely rotatable on the drive shaft I96, said flywheel being connected to said shaft through a manually controlled main clutch I91. When this clutch is engaged the machine is set in operation.

Serial N o.

-platen,rthe' sheets-then being discharged into A bevel gear I90 on the'drive shaft Ill meshes .with a bevel gear I99 'on the shaft 20a-which corresponds-to the shaft 20 in the form of the invention illustrated in Figs. 1 to 7. The various devices provided in the machine are operated from the shafts I96 and 20a. 1

The printing devices in the form of the invention are stored in a magazine M and are withdrawn therefrom by a feeding mechanism operated from the shaft 20iz.-Ari eccentric 2Ia is fast on the shaft 20 and is surrounded by an eccentric strap 22a carrying a connecting rod 23a to which the arm 24a of the printing device drive rocker 25a is pivotally connected. This drive rocker 25a corresponds to the drive rocker 25 shown in Fig; 2 and functions in like manner to bring about step by step advancing of the printing devices.

The platen P is carried by an arm corresponding to the arm 32 (Fig. 2) of a rocker like the rocker 33. This rocker includes two arms like the arms 35 and 36 that carry rollers like the rollers 3I and 38, which rollers are respectively engaged with the peripheries of conjugated cams like the cams 39 and 40, which cams are fast on a sleeve a that corresponds to the sleeve M. The sleeve lie is disposedabout the shaft 20a and is adapted to be connected thereto through a pawl like the pawl 43 which is engaged and disengaged under control of a throwout arm 41a which is similar to the throwout arm 41 (Fig. 3). In other words, when the throwout arm 41a is moved inwardly to the position in which it is shown in Fig. 12, it engages the tail of a pawl and interrupts operation of the platen P.

After a sheet'has been stopped by the last of the stop fingers 20I it moves into a printing couple C mounted on the frame of the machine and from this printing couple the sheets are discharged into a suitable collecting receptacle. The printing couple C may be of the kind, for example, disclosed in the application of Curtis George Kranz, Serial No. 404,092, filed November 1., 1929, now Patent 1,955,814, patented April 24,- 1934. It is to be understood, however, that any suitable printing couple may be used.

It is therefore apparent that a roll of paper may be mounted at one end of the machine and that a web may be led therefrom to be passed through a printing couple wherein impressions are made at spaced intervals on one face of the web. From this printing couple the web is directed through a pair of feeding rollers and a severing device and this severing device is operated to divide the web into sheets intermediate the impressions made thereon by the printing couple, this being so effected that the impressions are neatly oriented on one face of each of the sheets. The severed sheets are then moved along into printing position below a platen which makes impressions from printing devices on the face of the sheet opposite that from which impressions'were made by the printing couple.

Prior to the time the web is severed from the sheet it may be scored to divide it into a plurality of sections such as a main body and one or more stubs. The platen is operated to make an impression from each of said sections, the stop fingers 20I positioning the sheet for this purpose. After the platen has made an impression on each section of a sheet the sheet is then passed to the printing couple C wherein an impression is made on the same face of the sheet as that on which impressions were made by the the collecting receptacle. A step by step movement is imparted to th web to feed it through the severing device so that sheets of predetermined width are severed therefrom. Such step by step movement is imparted to the web by the feeding rollers as I9I. These rollers are in clamping engagement with each other so as to tightly clamp the web therebetween and are interconnected by pinions .having a one-to-one ratio so that when power is supplied to one of the rollers the other will be driven in synchronism therewith. To this end a pinion 202 is freely mounted on the shaft of one of the rollers and through a suitable clutch device 203 imparts rotative movement to the rollers when driven in one direction by the gear segment 204. The gear segment 204 is operated by a crank 205 which receives movement from a shaft 206 which has a bevel gear 201 that meshes with a bevel gear 208 on the jack shaft 209. This shaft 209 is driven from the drive shaft I96 in the following manner:

A clutch, generally indicated by 2I0 (Fig. 10) is mounted on the shaft I96. This clutch includes a collar 2 (Fig. 11) that is fast on the shaft I96 and which has a notch 2I2 in the periphery thereof. A gear 2| 3 is rotatably mounted on the shaft I96 and carries a. pawl 2 that is normally seated in the notch 2I2 and so long as this pawl is seated in this notch rotative movement is imparted to the gear 2I3 which meshes with a gear 2I5 fast on the shaft 209. Thus so long as the pawl 2I4 is seated in the notch 2I2 the shaft 209 rotates with the shaft I96. The gears 2I3 and 2I5 have a one-to-one ratio and therefore the shaft 209 rotates in synchronism with the shaft I96 as does the shaft 20a and the shaft 206, which latter shaft, as stated, is driven from the shaft 209.

The severing device consisting of the knives I92 and I93 is operated from the shaft 206 by a cam 2I6 (Fig. 13) which serves to reciprocate a bell crank 2", one arm of said bell crank being connected to the movable knife I93 through a link 2I8. This arrangement functions to lower the knife I93 and sever a sheet from the web intermediate feeding operations of the rollers as I 9|.

The printing couple including the cylinder I is also operated from the shaft 206, a gear 2I9 being fast on the shaft 206 and meshing with a gear 220 which in turn is connected to a gear 22I that meshes with a gear (not shown) on the shaft carrying the platen cylinder of the printing couple, and this gear meshes with a gear 222 on the shaft carrying the printing cylinder I90.

It will therefore be seen that the printing couple including the printing cylinder I90, the the feeding rollers including the roller I9I, and the severing device including the movable knife I93 are all operated from the shaft 209, the operation of which in turn is controlled by the pawl 2I4.

The. stop fingers 20I are operated by a cam shaft I'Ia (Fig. 12). In each cycle of operation the cam shaft I'Ia makes. as manyrevolutions as there are sections on the sheets S being printed in the machine. Thus if the sheets S are divided into three sections the cam shaft Ila makes three revolutions in each cycle. The cam shaft IIa is also driven from the shaft 209, it being provided with a bevel gear 223 that meshes with a bevel gear 224 fast on the shaft 209, the ratio between these gears being such as to bring about the required numberof operations of the camshaft llainacycleofoperationofthe machine.

the belts man: also driven from the mm! 2", a gear 22' being fast on the shaft 2" which, through the gear train 226, drives the shaft 221 on which the pulleys, about which the belts 2" are directed at one end of the machine, are passed (see Fig. 11).

It has been explained that the platen is to make an impression from each printing device in printing position selected to be printed onto each section of each sheet. Thus if the sheets are divided into three sections the three impres- 15 sions are to be made from each printing device fed into printing position and therefore in two cycles of operation of the machine the means eflecting operation of the rocker 254 are rendered inoperative.

It has been explained that the connecting rod 23a (Fig. 12) is connected to the arm 24a. This connection includes a sleeve 22! into which the connecting rod 23:: extends. A spring urged pawl 22! is mounted on this sleeve and normally 25 seats on a shoulder on the connecting rod 23a.

A pin 23. is provided on this pawl and is engageable by the arm 23! of the rocker, generally indicated by 232, which also includes an arm 2" having a roller 2 thereon engageable with a cam 23! on the cam shaft Ho. The cam 22! includes a flattened portion which, during .the last impression from a printing device, engages the roller 2 and thereupon so positions'the arm 23l that it is out of the path of the pin 230 which enablesthe pawl 22! to engage the'shoulder on the connecting rod 231:, and therefore in this cycle of operation the drive rocker 25a will be operated to advance the printing devices.

If a printing device fed into printing position 40 following such operation of the rocker 25a is to be printed, the cam shaft 21a rotates in the next cycle of operation and the cam 235 there-' upon so positions the arm 2 that the pawl 22! is held from connection with the shoulder on the connecting rod 23a until the cycle of operation in which the last impressions are made from this printing device. If, however, the printing device newly fed into printing position is not to be printed, the cam shaft I la does notrotate and the printing device newly fed into printing position is passed therefrom without an impression being made therefrom.

Thus so long as the pawl 2 is seated in the notch 2i2 the camshaft "a is operatedas well as the printing couple, the feeding rollers, the severing device and the conveyor belts, but when the pawl is unseated these mechanisms do not operate.

Whether or not the pawl 2 remains seated in the notch 2|2 depends upon the position of the throwout arm 236 (Fig. 11) and the positioning of this throwout arm is under control of this selector. An arm 23'! is connected to the throwout arm "a and is movable therewith into alternate positions. The arm 231 has 9. depending portion 238 on which a roller 239 is mounted. The roller 239 is engageable with a roller 240 on the throwout arm 236 which is pivotally mounted on the frame at 2. When thethrowout arm 41a is positioned to disconnect the sleeve a from the shaft 200. and thereby interrupt operation of the platen, the arm 231 is so positioned that the roller 22! engages the roller 2 and so positions the throwout arm 226 that the pawl 2 is unseated from the notch 2l2, Thus whenever the platen is inoperative, the

means operated from the shaft 2 through the net I! is provided which is controlled in the same manner as the electro-magnet TI. The armature 18 of this electro-magnet is connected to one arm of a bell crank I4 and one end of a link 2" is connected to them 13 of this bell crank.

When the electro-ma gnet I1 is energized under 7 conditions similar-to those previously described,

the armature I! thereof is attracted which rocks the bell crank 14 and the arm I2 thereof through the link 2" which thereupon so positions the throwout arms "a, 23. that the platen and the devices operated from the shaft 208 are rendered inoperative. This operation is timed to. occur only during the cycle in which the last impression is made from a printingdevice and in this manner all mechanisms in the machine except the printing device feeding means are renderedoperative. The printing device feeding means remains operative and advances the succeeding printing device into printing position in the succeeding cycle of operation when a printing device is to be skipped, All parts remain in the position in which they were stopped and therefore the timed relation therebetween is maintained just as is effected in the machine disclosed in the aforesaid Hartley patent.

Thus the mechanism disclosed in the Hartley Patent 2,002,737 can be readily controlled by the selector disclosed herein, it only being necessary to supplant the mechanically operating devices of the Duncan patent by devices controlling the electro-magnet' 11.

In the foregoing description I have described the use of a photo-electric cell in connection with a grid-glow tube but it is to be understood that the invention is not limited to the use of such a tube for an ordinary 'audion or other suitable amplifying means may be employed. Moreover, the invention is not limited to the use of a photoelectric cell as a selenium cell or other light sensitive means may be used.

In the described embodiments of the invention the movement of the printing devices is arrested during the time the selection is being performed but manifestly the detection may be carried out while the printing devices or other devices carrying identifying means are in motion. While I have illustrated and described a selected form of construction for my inventionit is to be understood that this is capable of variation and modification and I therefore do not means to regulate the operation of said operative means in accordance with the classification of the printing device disposed at selector position and embodying detecting means includ- 5 ing a source of light, light sensitive means adapted to be influenced by light from said source, means directing a beam of light from said source to "selector position and.concentrating said beam on the identifying means positions on the printl ing device at selector position, and means to control the passage of the beam of light to the identifying means positions on the printing device at selector position whereby only selected of said positions are .eflective in the regulation 15 of the operation of said operative means.
